Description

Technical Field

[0001] The utility model relates to the technical field of ground piles, and more specifically to a ground pile for solar photovoltaic installation with a stable connection. Background Art

[0002] Solar photovoltaic installation ground piles refer to the pile foundations used to support photovoltaic modules in solar photovoltaic power stations. Photovoltaic power stations require a large area of ​​ground to install photovoltaic modules, and ground piles are the supporting structures that fix photovoltaic modules to the ground. Ground piles are generally made of metal materials with high strength and durability. They are usually long and thin columnar structures with spiral surfaces. They can be installed underground by drilling or digging holes.

[0003] When installing existing photovoltaic modules, four ground stakes are usually required for fixing. The four ground stakes can be arranged in a rectangular diagonal line and connected to the mounting holes at the edge of the bottom of the photovoltaic module base, thereby providing the photovoltaic module with a relatively stable support and preventing the photovoltaic module from tilting to one side. However, photovoltaic modules have different models and sizes, and their base sizes are also different. For bases of different sizes, the distribution positions of the mounting holes at the bottom are naturally different, so the user needs to adjust the distance between the multiple ground stakes according to the positions of the mounting holes. The existing method is mostly to measure through measuring tools, but the efficiency is low, and in the process of installing the ground stakes, additional positioning tools are needed to ensure that the ground stakes enter the ground in a vertical posture, which is inconvenient.

[0004] Therefore, in order to solve the above problems, a ground pile for solar photovoltaic installation with stable connection is proposed. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a ground pile for solar photovoltaic installation with a stable connection. The device has a simple structure, a small size and is easy to carry. Through the arrangement of an outer extension rod and an inner extension rod, a user can quickly adjust the spacing between multiple positioning columns according to the size of the photovoltaic component, so as to realize rapid positioning of the installation position of the ground pile body. Since the positioning columns have a certain height, the ground pile body can always remain vertical during the process of drilling into the ground, and multiple ground pile bodies can be drilled at the same time. The limiting effect of multiple positioning columns on the ground pile body can prevent the spacing between multiple ground pile bodies from shifting during the drilling process, so that multiple functions can be realized simultaneously through the device, which brings convenience to the user's installation and improves work efficiency.

[0006] In order to solve the above problems, the utility model adopts the following technical solutions: A ground pile for solar photovoltaic installation with stable connection, comprising a plurality of ground pile bodies and a plurality of positioning columns, wherein the plurality of positioning columns are symmetrically distributed in pairs, and the inner ends of the plurality of positioning columns are engraved with spiral grooves matching the ground pile bodies, and an outer extension rod and an inner extension rod are arranged between two adjacent positioning columns, wherein the inner extension rod is slidably connected to the inner end of the outer extension rod, and the top ends of the outer extension rod and the inner extension rod are engraved with matching scale lines.

[0007] Furthermore, the outer end of the outer extension rod is threadedly connected to a limiting screw rod, and one end of the limiting screw rod extends to the inner cavity of the outer extension rod and abuts against the inner extension rod.

[0008] Furthermore, the positioning column includes an inner column and an outer column, and the outer column is arranged on the outer side of the inner column.

[0009] Furthermore, the plurality of outer extension rods are respectively fixedly connected to a pair of inner columns on the diagonal line, and the plurality of inner extension rods are respectively fixedly connected to another pair of inner columns.

[0010] Furthermore, a pair of mutually symmetrical docking blocks are fixedly connected to the inner end of the inner column, and a docking groove matching the docking blocks is formed at the inner end of the outer column.

[0011] Furthermore, a mounting block is fixedly connected to the outer end of the outer column, and a plurality of the mounting blocks are symmetrically distributed in pairs.

[0012] Furthermore, a support screw is threadedly connected to the mounting block, and a gasket is fixedly connected to the bottom end of the support screw.

[0013] Furthermore, a level bubble is installed at the top end of each of the plurality of outer extension rods.

[0014] Beneficial effect: Compared with the prior art, the advantages of the utility model are: the device has a simple structure, a small size, and is easy to carry. Through the arrangement of the outer extension rod and the inner extension rod, the user can quickly adjust the spacing between multiple positioning columns according to the size of the photovoltaic module, so as to realize the rapid positioning of the installation position of the ground pile body. Since the positioning column has a certain height, the ground pile body can always remain vertical during the process of drilling into the ground, and multiple ground pile bodies can be drilled at the same time. The limiting effect of the multiple positioning columns on the ground pile body can avoid the displacement of the spacing between the multiple ground pile bodies during the drilling process, so that multiple functions can be realized at the same time through the device, which brings convenience to the user's installation and improves work efficiency.

[0015] In this solution, the outer extension rods and the inner extension rods located on the long sides and the wide sides can be adjusted to different lengths, so as to adapt to photovoltaic modules with square bases or rectangular bases of various sizes, thereby improving the practicality of the device.

[0016] In this solution, by setting up multiple level bubbles and multiple support screws, the heights of multiple positioning columns from the ground can be adjusted separately, so that the multiple positioning columns can be roughly in the same horizontal position, so that the multiple ground pile bodies that are finally installed can also be roughly in the same horizontal position, making the photovoltaic components installed subsequently more stable and avoiding large tilts.

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1-3, including multiple ground pile bodies 1 and multiple positioning columns 2, the multiple positioning columns 2 are symmetrically distributed in pairs, and the inner ends of the multiple positioning columns 2 are engraved with spiral grooves matching the ground pile bodies 1, an outer extension rod 3 and an inner extension rod 4 are arranged between two adjacent positioning columns 2, the inner extension rod 4 is slidably connected to the inner end of the outer extension rod 3, and the top ends of the outer extension rod 3 and the inner extension rod 4 are engraved with matching scale lines, the outer end of the outer extension rod 3 is threadedly connected to a limiting screw 5, one end of the limiting screw 5 extends to the inner cavity of the outer extension rod 3 and abuts against the inner extension rod 4.

[0026] Solar photovoltaic installation ground piles refer to the pile foundations used to support photovoltaic modules in solar photovoltaic power stations. Photovoltaic power stations require a large area of ​​ground to install photovoltaic modules, and ground piles are the supporting structures that fix photovoltaic modules to the ground. Existing photovoltaic modules usually require four ground piles for fixation during installation. The four ground piles can be arranged in a rectangular diagonal shape and connected to the mounting holes at the edge of the bottom of the photovoltaic module base, thereby providing a more stable support for the photovoltaic module. Photovoltaic modules have different models and sizes, and the distribution positions of the mounting holes at their bottom are naturally different. Therefore, users need to adjust the distance between multiple ground piles according to the positions of the mounting holes, and ensure that the ground piles enter the ground in a vertical posture.

[0027] In this solution, the user can carry the device to the location where the photovoltaic module needs to be installed, and adjust the multiple inner extension rods 4 and outer extension rods 3 according to the position of the installation hole of the photovoltaic module base. By pulling the outer extension rod 3 to slide in the inner cavity of the inner extension rod 4, the outer extension rod 3 and the inner extension rod 4 can be extended or shortened. By observing the sum of the scales shown on the outer extension rod 3 and the inner extension rod 4, the current length of the outer extension rod 3 and the inner extension rod 4 can be determined. The user can adjust the length to be the same as the spacing between the photovoltaic module installation holes, and then fix the outer extension rod 3 and the inner extension rod 4 by tightening the limit screw 5. The outer extension rod 3 located on the long side and the wide side The inner extension rod 4 can be adjusted to different lengths to adapt to photovoltaic modules with square bases or rectangular bases of various sizes. Then the user places multiple positioning columns 2 at the positions where ground piles need to be driven, and then spirally embeds multiple ground pile bodies 1 into the inner ends of multiple positioning columns 2 respectively. Then the ground pile body 1 can be drilled into the ground through the pile driving device. Since the positioning columns 2 have a certain height, the ground pile body 1 can always remain vertical during the process of drilling into the ground, and multiple ground pile bodies 1 can be drilled at the same time. The limiting effect of the multiple positioning columns 2 on the ground pile body 1 can prevent the spacing of the multiple ground pile bodies 1 from shifting during the drilling process.

[0028] See also Figure 2-5The positioning column 2 includes an inner column 201 and an outer column 202. The outer column 202 is arranged on the outer side of the inner column 201. A plurality of outer extension rods 3 are respectively fixedly connected to a pair of inner columns 201 on the diagonal line, and a plurality of inner extension rods 4 are respectively fixedly connected to another pair of inner columns 201. A pair of mutually symmetrical docking blocks 203 are fixedly connected to the inner end of the inner column 201, and a docking groove 204 matching the docking block 203 is opened at the inner end of the outer column 202.

[0029] Before the user completely embeds the multiple ground pile bodies 1 into the ground, the user needs to take out the multiple positioning columns 2. The user can temporarily stop embedding the multiple ground pile bodies 1 after they are embedded into the ground for a certain distance, and then remove the multiple outer columns 202 from the outer ends of the multiple inner columns 201 respectively, so that the docking block 203 is disengaged from the docking groove 204. Then the user loosens the pair of limit screws 5, and then shrinks the lengths of the multiple outer extension rods 3 and the inner extension rods 4, so that the multiple inner columns 201 move toward the inner side of the multiple ground pile bodies 1, so that the multiple inner columns 201 are separated from the ground pile bodies 1. Then the user can take out the multiple positioning columns 2 and the multiple outer extension rods 3 and the inner extension rods 4 from between the multiple ground pile bodies 1, and continue to complete the drilling of the multiple ground pile bodies 1.

[0030] See also Figure 4 The outer end of the outer column 202 is fixedly connected with a mounting block 7, and multiple mounting blocks 7 are symmetrically distributed in pairs. A support screw 8 is threadedly connected to the mounting block 7, and a gasket is fixedly connected to the bottom end of the support screw 8. The top ends of the multiple outer extension rods 3 are all installed with level bubbles 6.

[0031] After placing the plurality of positioning columns 2 at the desired positions and before rotating into the ground pile body 1, the user can determine whether the plurality of outer extension rods 3 are in a horizontal state by observing the plurality of level bubbles 6, thereby determining whether the plurality of positioning columns 2 are in the same horizontal position. If they are not in a horizontal state, the user can rotate the support screws 8 on the plurality of mounting blocks 7 to move the support screws 8 downward, and prop up the positioning columns 2 through the gaskets at the bottom ends of the support screws 8. By adjusting the plurality of support screws 8, the heights of the plurality of positioning columns 2 are adjusted respectively, and at the same time, the plurality of positioning columns 2 are made roughly horizontal by observing the level bubbles 6. With such a setting, the user can During the process of drilling into the ground pile body 1, it can be determined whether the multiple ground pile bodies 1 are in a horizontal position by observing the distance between the top ends of the multiple ground pile bodies 1 and the positioning posts 2. Then, after the user removes the positioning posts 2, the user can determine whether the ground is tilted by observing whether the distances between the multiple ground pile bodies 1 in a horizontal position and the ground are roughly the same, thereby appropriately adjusting the final drilling depth of the multiple ground pile bodies 1, so that the multiple ground pile bodies 1 that are finally installed can be roughly in the same horizontal position, thereby making the photovoltaic components installed subsequently more stable and avoiding a large tilt.

[0032] Working principle: When in use, the user can carry the device to the location where the photovoltaic module needs to be installed, and adjust the multiple inner extension rods 4 and the outer extension rods 3 according to the position of the installation hole of the photovoltaic module base. By pulling the outer extension rod 3 to slide in the inner cavity of the inner extension rod 4, the outer extension rod 3 and the inner extension rod 4 can be extended or shortened, and the length of the outer extension rod 3 and the inner extension rod 4 is adjusted to be the same as the spacing between the installation holes of the photovoltaic module, and then the outer extension rod 3 and the inner extension rod 4 are fixed by tightening the limit screw 5, and then the multiple level bubbles 6 are observed to determine whether the multiple outer extension rods 3 are in a horizontal state. If they are not in a horizontal state, the user can rotate the multiple installation blocks The support screw 8 on 7 is used to move the support screw 8 downward, and the positioning column 2 is propped up by the gasket at the bottom end of the support screw 8. The heights of the multiple positioning columns 2 are adjusted respectively by adjusting the multiple support screws 8. At the same time, the multiple positioning columns 2 are made roughly horizontal by observing the level bubble 6. Then the user places the multiple positioning columns 2 at the positions where the ground piles need to be driven, and then the multiple ground pile bodies 1 are respectively screwed into the inner ends of the multiple positioning columns 2. Then, the ground pile bodies 1 can be drilled into the ground through the pile driving device. Since the positioning columns 2 have a certain height, the ground pile bodies 1 can always remain vertical during the process of drilling into the ground, and multiple ground pile bodies 1 can be drilled at the same time. Before the ground pile body 1 is completely embedded in the ground, the embedding can be temporarily stopped after the multiple ground pile bodies 1 are embedded in the ground for a certain distance, and then the multiple outer columns 202 are respectively removed from the outer ends of the multiple inner columns 201 to disengage the docking block 203 from the docking groove 204. Then the user loosens the pair of limit screws 5 and shrinks the lengths of the multiple outer extension rods 3 and the inner extension rods 4, so that the multiple inner columns 201 move toward the inner side of the multiple ground pile bodies 1, so that the multiple inner columns 201 are separated from the ground pile bodies 1. Then the user can take out the multiple positioning columns 2 and the multiple outer extension rods 3 and the inner extension rods 4 from between the multiple ground pile bodies 1, and continue to complete the drilling of the multiple ground pile bodies 1. Since the multiple positioning posts 2 are approximately in the same horizontal position, the user can determine whether the multiple ground pile bodies 1 are in a horizontal position by observing the distance between the top of the multiple ground pile bodies 1 and the positioning posts 2 before removing the positioning posts 2. Then, after the user removes the positioning posts 2, the user can determine whether the ground is tilted by observing whether the distances between the multiple ground pile bodies 1 in a horizontal position and the ground are approximately the same, thereby appropriately adjusting the final drilling depths of the multiple ground pile bodies 1, so that the finally installed ground pile bodies 1 can be approximately in the same horizontal position, thereby making the photovoltaic components installed subsequently more stable and avoiding a large tilt.

[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
